Abstract: Production of yellow bis-(3-(triethoxysilyl)-propyl)polysulfane (average sulfur chain length less than 4 and iodine color number no greater than 10 mg iodine/100 ml) comprises mixing neutral chloropropyltriethoxysilane with chloropropyltrichlorosilane and reaction with sodium sulfide and sulfur, disodium tetrasulfide and Nas2S or disodium trisulfide and Na2S in ethanol. A process for the production of yellow bis-(3-(triethoxysilyl)-propyl)polysulfone having an average sulfur chain length of less than 4 and an iodine color number of no greater than 10 mg iodine/100 ml comprises mixing neutral chloropropyltriethoxysilane with chloropropyltrichlorosilane followed by reaction with sodium sulfide (Na2S) and sulfur, disodium tetrasulfide (N2S4) and Nas2S or disodium trisulfide (Na2S3) and Na2S in ethanol.
